usb: gadget: udc: Remove useless variable assignment in xudc_read_fifo()
This patch removes the unused variables assignment warning. Value assigned to variable bufferspace is overwritten, before it can be used. This makes such variable assignment useless. Reported Coverity warning: UNUSED_VALUE Signed-off-by: Piyush Mehta <piyush.mehta@xilinx.com> Link: https://lore.kernel.org/r/20220506175349.10102-1-piyush.mehta@xilinx.com Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
